英文摘要：

Frames consisting of reinforced concrete columns and steel beams （RCS） is a new type of composite structures. It provides several advantages over conventional steel and concrete moment resisting frames with lower cost and more efficient in both design and construction stages. Background of the research and applica- tion of the RCS composite joints and composite frames was overviewed detailedly in this paper. Then the research evolution of the RCS composite joints including experimental research and numerical simulation in A- merica, Japan and China was described in detail. Also the seismic behavior of the RCS composite joint was introduced based on the result of experimental research and numerical simulation. Finally some existing problems and the development directions of research on RCS framing systems in the future were pointed out.
